The thermoplastic elastomers of the invention are from the group consisting of C 2 -C 8 -α-olefins, C 4 -C 15 -diolefins, and other monomers, using metallocene compounds of formula I or formula XIII or? Complexes It can be prepared by bulk, solution, slurry or gas phase (co) polymerization of the monomers.n n n <Formula I>n n n n n n n n <Formula XIII>n n n n n n n n (In the above formula,n n n CpI and CpII are carbanions with cyclopentadienyl containing structures,n n n πI and πII are charged or electrically neutral π-based,n n n D is a donor atom,n n n A is a receptor atom,n n n Where D and A are connected in a reversible coordination bond such that the donor has a (partially) positive charge and the receptor has a (partially) negative charge,n n n M is a transition metal of the III, IV, V or VI subgroups of the Periodic Table of the Elements (Mendellib), including the Lanthanides and Actinides,n n n X is an anion equivalentn n n n is 0, 1, 2, 3 or 4 depending on the charge of M) |
